I married into a Greek Orthodox family as a non believer and developed more of an interest in Christianity over the last few years. I wanted to do my research on denominations so started with Anglicanism being an Englishman and all, but all you have to do is look at the CoE to see how well that is going. Protestantism didn't make any sense as they seem to think you only need the Bible, not the church, but it was the church that constructed the Bible, so for me it came down to Catholicism and Orthodoxy. Long story short is whether you agree with the infallibility of the papacy and I don't think the evidence in favour holds up. Orthodoxy follows the ways of the church pre schism, even most Catholics agree on that but think the papacy has authority to change things. Thats why I leant into Orthodoxy and haven't regretted it one bit. As for the service in Greek, my church does Saturday service in English as there are other English converts and other non Greek attendees and the other services in Greek are still lovely, the same way a traditional Latin mass would be for Catholics. I would definitely encourage you to check out your local Orthodox Church 🙏🏻☦️
